The problem with this poll is that for those who don't know any English at all, they would not understand which poll option corresponds to "not at all". But of course they probably wouldn't understand the question.
The one poster who I did have to read several times to understand was Master Yoda.
The thing is as I observed in GM, there were many posters like him in the history of MTF, seemed to write longer paragraphs but struggled to understand such basic things. I called them "fuctional illiterates" in myself and often they show the tendencies, which in-real-life FIs are characteristic of. Not really a matter for astonishment, since sports/tennis fans often can be so basic as rarely experienced on any other realms of life.
